Re: Make LED matrix array using a single microcontroller
Think about it as this. You TV refreshes the display 25 times per second. With two fields, it is like 50 fields per second. With a microcontroller, How fast you think you can refresh these LED displays ? That's how this scanning method work. Though it can be logically thought as drawing to one displ...

Ateml AVR GPIO operations quick guide
All port B pins as output (Direction register) DDRB = 0xff; All port pins set to 1 (ON) PORTB = 0xff; Set port D pin 2 as output DDRB |= 1 << DDB2; Set port D pin 2 as input DDRB &= ~(1 << DDB2); Set port B pin 2 to 1 (ON) PORTB |= _BV(PB2); OR PORTB |= 1 << 2; OR PORTB |= 1 << PINB2; Set port B pin...

Atmel AVR ADC sample code
An ADC, or Analog to Digital Converter, allows one to convert an analog voltage to a digital value that can be used by a microcontroller. There are many sources of analog signals that one might like to measure. There are analog sensors available that measure temperature, light intensity, distance, p...

TSL230R: Photographic Conversions
In the previous post on using the Taos TSL230R with the Arduino, I covered the basic operations of the chip, and some essential conversions for going from radiometric to photometric representation of its data. In this post, we’ll expand on that knowledge to calculate exposure times and apertures usi...

Taos TSL230R light sensor C tutorial
The TSL230R light sensor IC is an interesting package: a light sensing circuit wrapped up in a clear plastic casing. This neat little device will convert irradiance (the light energy on the surface of the sensor) into frequency. Working with a simple input concept like a frequency means that we won’...
